# Operation Jeb Stuart III

Operation Jeb Stuart III was a U.S. Army operation during the Vietnam War conducted by the 1st Cavalry Division. It took place in Quảng Trị and Thừa Thiên Provinces of I Corps, South Vietnam from 17 May to 3 November 1968.

## Background

Following the completion of Operation Pegasus (1–14 April), Operation Delaware from 19 April to 17 May and Operation Concordia Square (8–17 May), the 1st Cavalry Division returned to the coastal lowlands of Quảng Trị and Thừa Thiên Provinces. The objective was to engage People's Army of Vietnam (PAVN) forces in their Base Areas 101 and 114, located west of Quảng Trị and Huế. This was originally the objective of Operation Jeb Stuart, but the Tet Offensive had disrupted these plans, leading the Division to participate in the Battle of Quang Tri and the Battle of Huế.
